Posted July 14, 20169 yr So i am making a mod to make building in survival easier and i am working on an item that changes the biome of the block right clicked. I have searched on google and on the forums but i havent found a way to change the biome after world generation. As far as I know minecraft doesnt normally do this so i dont know if it's even possible. Any suggestions would be nice.
July 14, 20169 yr Biomes are stored in the Chunk#blockBiomeArray field. Use World#getChunkFromBlockCoords to get the Chunk at the specified position, then use Chunk#getBiomeArray to get the biome array. This array stores the ID of the Biome at each x/z position within the chunk, using (z & 15) << 4 | (x & 15) as the index. Use Biome#getIdForBiome to get the ID of a Biome . Please don't PM me to ask for help. Asking your question in a public thread preserves it for people who are having the same problem in the future.
July 14, 20169 yr Author It crashes when i use this code im sure its because of how im setting the biome but im not sure how i should do it. worldIn.getChunkFromBlockCoords(pos).getBiomeArray()[index] = (byte) Biome.getIdForBiome(new BiomeSnow(true, null));
July 14, 20169 yr It crashes Crashlog? I made the Mob Particles mod, you can check it out here: http://www.minecraftforum.net/topic/2709242-172-forge-mob-particles/
July 14, 20169 yr Author Im an idiot and forgot to post it so here it is http://pastebin.com/Xueb4Fjq
July 14, 20169 yr Author Nevermind i figured it out i had to use worldIn.getChunkFromBlockCoords(pos).getBiomeArray()[index] = (byte) Biome.getIdForBiome(Biomes.COLD_TAIGA); instead.
July 14, 20169 yr Yeah, no shit. Creating a new biome instance is not the same as referencing an existing instance. Apparently I'm a complete and utter jerk and come to this forum just like to make fun of people, be confrontational, and make your personal life miserable. If you think this is the case, JUST REPORT ME. Otherwise you're just going to get reported when you reply to my posts and point it out, because odds are, I was trying to be nice. Exception: If you do not understand Java, I WILL NOT HELP YOU and your thread will get locked. DO NOT PM ME WITH PROBLEMS. No help will be given.
